ABSTRACT:
A semiconductor integrated circuit device includes: a target circuit whose at least power supply voltage is variable; a power supply voltage providing circuit feeding the target circuit with a power supply voltage; and a minimum energy point monitor circuit detecting an energy-minimizing power supply voltage which minimizes a change in the energy consumed by the target circuit upon a change in the power supply voltage. The power supply voltage delivered by the power supply voltage providing circuit is controlled so as to be equal to the energy-minimizing power supply voltage detected by the minimum energy point monitor circuit.
